Yosemite’s Switch to Core Storage

Craig Cohen (via Clark Goble):

Yosemite uses a volume format known as Core Storage. It is the enabling technology behind Fusion Drive and FileVault.

Core Storage is a reliable, high-performance volume format. It provides increased crash protection, ditto blocks for metadata, copy-on-write B-tree catalogs, in-place transformations for backgrounding the disk encryption used by FileVault, and intelligent block-level data migration used by Fusion Drive.

Yosemite will auto-convert your drive so long as your Mac has hardware support for encryption. HFS+ is still there; it’s just wrapped in another layer.
